Geeze, first I thought I had to buy Samsung products to support them in their fight against Apple, now I have to buy MMI products too? I'm going to go broke trying to support companies that anger Apple. Maybe it's cheaper and easier to just go to the dark side and buy an iPhone and move into the Apple Ecosystem.
Child porn is illegal because its production requires the molestation of a child
So why is possession illegal? I can get behind making production of child pornography illegal, since it involves child abuse; but the arguments for making possession illegal are as laughably out of date as classifying cryptography as "munitions."
I believe the reasoning is that without a market of people that want to watch it, there would be much less incentive to create it. Maybe there's not 100% correlation,. but it seems like a reasonable restriction to help prevent child abuse.
Plus there are other valid reasons for not allowing possession of child pornography - for example, if the name of the child in the video is known, it can cause them even more harm when their forced sex acts are available for viewing by anyone that types their name into a search engine.
I'm not sure how you made the analogy between cryptography and porn (other than the fact that strong crypto can be used to hide your porn collection)
That is true, the OS is open source, but you need a license agreement in place to distribute all of the google apps (i.e. gmail, google maps, goggles, talk, etc. etc.) with your device/rom. You WILL NOT be able to make a commercially succesful tablet / phone once you lose the right to bundle those apps stock!
I bet Amazon would be interested in providing the default app store.
Why? They have their own app store, why would they want to give app revenue to Google? Does Amazon want me to install the Nook application on my Kindle?
'I'd still feel better if they had their emergency checklist on their lap to make sure that they follow all procedures and don't get so focused on shutting down the bad engine that they forgot to set the flaps appropriately and end up in a stall upon approach.'
Captain: "Oh dear, we've lost an engine as we approach to land!"
F/O: "Gracious, it appears I've spilled battery acid on the laminated emergency checklist, and it is now completely unreadable!"
Captain: "In an unfortunate coincidence, our two iPad's and our on-board computer with redundant everything all failed simultaneously! Without those, I have no idea how to fly this pig!"
F/O: "I have no clue what to do in this situation! Even though I've got 5,000 hours of flying experience, and have to do recurrent simulator emergency training dealing with situations just like this one every six months, I have no idea how to handle an engine failure unless another pilot reads me the steps from a list!"
Captain: "We're going to die! We're all going to die!"
Pilots don't train for every possible emergency and sometimes they do need to be told what do do, even when it's common sense. Like not pulling up the nose keeping the plane in a stall while the stall warning horn is blaring.
In that particular case there probably wasn't time to consult any checklist, but sometimes a checklist reminds the pilot about what he's supposed to do in a stressful situation. If an experienced pilot always knows what to do based on his vast experience, why have checklists at all? Pilots go through the preflight checklist hundreds of times, yet they still use them. They may only go through some out-of-the-ordinary procedures once in a career (or never) outside of a simulator.
From the article 'I am pleased to say that we have now had further information from our technical team which means that we will be able to offer the same mitigating measures mentioned in relation to X5 and X6, to any concerned BMW owners, starting within the next eight weeks. This will mean that the car cannot be taken using the piece of equipment you highlight. Of course this will not render the car unstealable, but it will address this particular form of attack.'
Meaning they have already rendered this thing useless. Until the criminals figure out a way around it...
Well, I think you mean they *think* they will be able to render this attack useless starting in about 2 months from now, but until their fix makes it into the wild, they really don't know if someone will find an easy way around it.
Not only would Google's self-driving car be vulnerable to this attack, it would start driving around itself! And you would be responsible for everything the hacked vehicle did.
I agree with the previous note. It raises some very interesting points and why Google's self-driving cars would be bad. Just imagine if someone hacked your car and it ran over someone.
With computer control of conventional cars becoming more common (automatic braking, etc), and fly by wire making inroads (throttle control for now, eventual braking and steering), I'm not sure that hacking an auto-driving car is much worse than hacking any other car since the car will be able to take control from the driver.
While their tax treatment is certainly complicated, the taxation schedule isn't - you still aren't taxed until you liquidate the stock.
Not true, if you exercise an ISO and are subject to AMT, it's due in the tax year that you exercise the options, even if you don't sell the stock. Laws are changing and that may not be true in the future.
Look at the Cleveland Child abuse scandal, where some nutter from social services started doing anal dilatation tests on kids and got it into her head all these kids were being abused up the bum, because she'd just been on a course and pumped full of BS.
Wow. I'd never heard of that before.
How could a medical doctor seriously think that sexual abuse is the primary cause of anal dilation? There's another much more obvious and likely cause, and children are not immune to constipation. How many cases of children who really *were* victims of sexual abuse were not investigated because they didn't fail the anal dilation test? The test itself sounds traumatic to a child, and if it was done unnecessarily it probably counts as sexual abuse itself.
Those thrillers and spy stories are at least sold as fiction. And James Bond's actions and adversaries are often so over-the-top that they can not be considered realistic.
I'm no connoisseur of written porn (though i do have a healthy (unhealthy?) collection of adult videos), but I assume the porn in question sold as fiction and the subject matter is over-the-top by nearly everyone's standards.
Now how about shows like Future Weapons that glorify actual death and destruction? They like to demonstrate all kinds of modern weaponry showing off how well it destroys objects, and discussing on how efficient it is in killing people.
But since they aren't actually killing people on the show, wouldn't that be more like a porno movie showing people having sex with watermelons but saying that the watermelons were stand-ins for children?
Feel free to say goodby to other great books. Add them to the list.
It's OK, it for the good of the children...
He specifically excluded some existing literature:
Only "absolutely vile" material would be targeted, he said, adding by way of example that well-known novels such as Vladimir Nabokov's Lolita - which explores a middle-aged man's obsession and sexual involvement with a 12-year old girl - would not be covered.
Though it's not clear how that law would decide what is "absolutely vile" and what's not, as I'm sure there are some people that think Lolita is absolutely vile, and others that would not find any porn to be vile.
It's about time someone is passing a law against any written words about any illegal or illicit activity. Let's burn all the crime mysteries since they just foster and encourage people to commit crimes and murders. And those thrillers that glorify spies and espionage are a clear threat to governments anywhere. Any book that describes any immoral activity should be immediately banned as well, if no one reads about adultery they'll never commit adultery.
From now on, only stories about unicorns and rainbows should be allowed to be published.
Child abuse is abhorrent and should be severely punished, but is there any evidence that reading any type of extreme (or non-extreme) porn leads one to perform that activity?
You seem to have missed my point that I have had a bad experience with performance when using a hardware RAID controller. I got a lot of support from the vendor, who agreed that I was using appropriate enterprise-class drives. Eventually the conclusion from the vendor was that RAID cards were built to optimise certain types of usage at the cost of poor performance for other types of usage.
Well, that's the difference between rolling your own RAID array and buying from the big three -- you won't be talking to the RAID vendor, you'll be talking to the company that built your system, and when they isolate the performance problem, they'll get custom firmware from the RAID card maker and/or the drive manufacturer.
Apparently what I was doing (or rather, what the company I was working for was doing) just didn't fit into the envelope of performance for that card.
What is this special use case?
In my experience, hardware RAID has other disadvantages: flexibility -- can you re-shape or extend your array with a hardware card?
If that's important to you, then choose a RAID card that supports online RAID expansion (Promise supports it, I'm sure others do). I don't really trust online RAID expansion (whether software RAID or hardware RAID), but if you want to do it, you can find a card that will handle it.
I am also at the mercy of the hardware vendor when it comes to the tools used to manage the RAID system.
True, but I haven't found that to be limiting.
You give examples of time when a hardware RAID card would save data loss when software RAID would not, but what if the RAID card's cache is full when the power goes off? You are still going to lose data.
You seem to not understand how write-caches work, they don't become "too full". The only time a write is acknowledges is when it's safely stored in cache (or disk). If there's no room left in the cache, your write will wait until other data is written from the cache and space is available for your new data. There is never be a case when the cache is over full and data can be lost, even in the event of a power failure. If you're regularly filling the write cache on your controller, you probably need a higher performance disk subsystem for your workload.
It is true, however that with a battery backed cache, you can lose data after a sustained power failure (most BBU's are good for at least 72 hours, so if you don't get power to the server and shut it down cleanly within 72 hours, you'll lose data.
Perhaps your examples are corner cases? Arguably, the RAID card is more complexity and more to go wrong on the system. What if the RAID card dies when writing data?
Yes, there are advantages to hardware RAID, but pretending that there are no downsides is not realistic.
You think the RAID drivers in your operating system don't add complexity? The RAID controller has the advantage of its own SAS controller so the firmware only needs to work well with that one controller, also, when you buy a system from one of the big 3 vendors, the hard drive firmware is also qualified with the RAID card.
When the RAID controller fails, it's the same thing that happens when your SAS or SATA controller fails - your application can't write data and could lose data. I've got dozens of servers with dozens of RAID controllers, and haven't had a RAID controller failure yet. They are not the quirky beasts they used to be, they just work (though I do keep up with firmware updates).
I never said hardware RAID is perfect for every use case, but I haven't run across any cases where it's detrimental. The extra cost is minimal on any enterprise server. If pinching pennies is important, then software RAID may be your best choice.
She'd be entitled to any gains the stock made after they were married
you know what would be awesome? law says the partner is entitled to any gains made while married to be fair, they should be liable for any losses incurred while married as well
In California, spouses are liable for their "community" debt. Though I suspect that you're referring to FB's drop in stock value after the IPO but I see no way that could be construed as debt that he and/or his wife would owe.
When I saw the name McAfee Social Protection I thought it was going to be an app that helped prevent me from exposing my social data more widely than I wanted to -- something that monitors Facebook (and other) security settings and warns me if something changes in how public any of my data is. Something like that would be truly useful because I don't want to have to keep up with the changing privacy policies and security settings of every site I put my data on.
I have a simpler and more effective way to keep private pictures private -- I literally keep them private and I don't post them on social networking or photo sharing sites.
Anything that can be viewed on the screen can be copied through the analog hole of just taking a photo of the screen so if it's viewable there's no way to keep it private. (though I'm sure some day all cameras will have built-in copy protection similar to what is used to prevent currency from being copied and all recording devices will use similar schemes to prevent copyrighted audio from being copied, thereby closing the analog hole)
I have seen really terrible performance on real hardware RAID cards using enterprise-class hard drives. And, yes, I am 100% certain that it was not a fakeRAID controller card.
Hardware RIAD in not a magic bullet for performance and they come with a nuymber of disadvantages (your RAID controller dies: good luck getting the data off the disks).
What kind of workload were you running? As I said, hardware raid is typically faster than software raid, especially for writing to RAID-5/6 volumes. If your workload is mostly read-only, then you may not see much (if any) improvement with hardware RAID.
I use RAID to protect me from server downtime more than to protect my data - even if I have redundant servers, if one server in an HA pair is down, then I have no redundancy left so I use RAID (sometimes with dual controllers), dual power supplies, etc to help ensure that the server stays up. If the server is down anyway, I'm just going to restore data from backup rather than try to recover the data after I replace the card.
In real life? Not as likely as you wish it was, and the inverse square law fully applies. I just don't see this as anything other than a sales gimmick. People should be glad that most things can be charged via USB these days instead of being forced to use proprietary chargers.
If I'm reading their chart right, if the coils are 5cm in diameter, then they just need to be within 5mm of each other for 90% efficiency (5mm / 50mm = 0.1)
5mm seems more than reasonable for a charging mat, even with a case on the phone. That gives you 1mm to cover the coils in the mat, and up to 4m for the case and back of the phone.
A company is only as good as its employees, and having demotivated employees is not good for any company. If the employees are underwater on their stock for the forseeable future, it's going to be hard to keep them motivated.
What part of Zuck's business plan seems to imply he's in it for the long haul?
The fact that he structured the deal to maintain majority control of the company? Why would he institute such a plan (and alienate some large investors) if he wasn't planning to retain control? If he really wanted to cash in his billions and move on, there are better ways to ensure an orderly transition that would have been better for everyone, including himself.
Then no offense, but your interjection to change the subject of this thread to be about the company was somewhat inappropriate, considering the three posts above yours.
No offense, but I assumed that someone would read the first few words of my post: A company is only as good as its employees.
Sorry if that made it sound like I was saying that Zuckerberg's wealth is connected to the health of the company. I kind of thought I made that clear that Zuckerberg doesn't need FB to remain rich when I said Zuckerberg is set for life, there's no doubt
But if changing the topic of conversation within a thread is not permissible, then you should read to the very top of the thread where it was stated that the IPO was a success for Facebook the company: Hardly, the IPO was an amazing success for facebook. And I pointed out that just because they made lots of money doesn't necessarily mean that they made out well. For example, they've pretty much slammed the door on any chance of a secondary offering for the forseeable future.
I know. It is crazy! No hardware RAID is running any sort of software on it, right?? That would be batshit crazy!! It is all baked into the fabric of spacetime.
I trust my single-purpose RAID controller card a lot more than my general purpose operating system to get the write right.
Software RAID can't have battery backup. No sirreee! Those UPS things are not for commodity hardware anyway, only for big iron.
A UPS is not infallible since your server's operating system is subject to other failures such as someone yanking the power cord(s), hitting the reset button on the server, or an operating system crash. A hardware RAID card is not subject to any of these failures, if the power is yanked before it writes data, it will remain in the cache to be retried when the disks are available.
And journaling file system?? That only exists on the hardware from the big 3! Software RAID 1 implodes into a tiny blackhole everytime you run your rsync. Everyone knows that!
Filesystem journalling is independent of RAID level, most people using a journalling filesystem on top of RAID to protect against filesystem corruption from a server crash, which has nothing to do with RAID level. Typically only the filesystem metadata is journalled, so data corruption is still possible even with journalling. (data journalling is possible, but is rare since it means writing a second copy of data. Well actually I guess the RAID controller write cache is somewhat like a data journal)
Another advantage of Hardware RAID is that it's typically much faster than software RAID especially with RAID-5 and 6. Your write only has to hit the cache on the RAID controller to be "complete", while a less-than-full-stripe write with RAID-5 means reading the stripe, calculating parity then rewriting the entire stripe, so each write is really 3 I/O's and the I/O's all have to complete before you can declare the write complete. (I'm assuming NVRAM or battery backed cache RAM, if you use a RAID controller without it then you get what you deserve)
Software RAID has its place, but a hardware RAID controller (a real one, not fake-RAID) adds so little to a typical enterprise server's price that it's generally worth using.
A company is only as good as its employees, and having demotivated employees is not good for any company.
You seem to have a mistaken assumption that his company's employees are his top concern. Considering no one seems to bat an eye at the assumption that he's "set for life", I don't think such altruistic matters concern him in the slightest.
I was talking about the company, not Zuckerberg. The only reason he needs to care about the company so he can keep a few more of his billions of dollars. If he walked away from the company tomorrow, he'd still have billions of dollars to his name (and the company stock would likely drop in the short term, but depending on who takes over, it could help in the long term), but his ego probably won't let him do that - he'll want the company to succeed and grow with him at the helm. But there's pretty much nothing that could happen to the company now that will prevent him from being a billionaire -- it would take an extraordinary act to make the company's stock value to drop far enough to take him out of the billionaire range.
Search for your own. Priced one from hp/dell and it would have cost $6,000 plus. Built it with the same specs for $3000. That right there is why their server sales are dwindling.
The difference is not always so dramatic.
My local whitebox builder can put together hardware equivalent to a Dell R720: dual E-2620 CPU's, 32GB RAM, dual 1TB disks with onboard RAID (i.e. fake RAID) for $2800 with one year carry-in warranty. Dell charges $3566 for the the equivalent server but includes a 3 year next business day on-site warranty.
So the dell costs $766 more, or think of it as $20/month for on-site service.
If you're a large shop (or a very small shop) and don't mind taking care of motherboard swaps, etc yourself, then paying extra for Dell's support probably isn't worth if, but if you're a small shop with a dozen servers, you may not want to dedicate one of your (few) sysadmin's to a day of unracking the server and driving it across town for support, or procuring a replacement motherboard (if it's still available in 2 years) and swapping it out himself.
And when I buy the Dell, I'm less worried about build problems, like leaving a tangle of power cords dangling in front of the cooling fan (which I've seen happen on whitebox builds).
OK only 2% pee!! still do you want to drink it? the analogy is sufficient to make the point, it is not a whole solution to use in a comparison. It's just a way to illustrate to those who are not able to grasp the concept (like yourself or a child).
I'd rather drink a glass of sterile 2% pee than a glass of 2% oil.

Something like that would be truly useful because I don't want to have to keep up with the changing privacy policies and security settings of every site I put my data on.
I have a simpler and more effective way to keep private pictures private -- I literally keep them private and I don't post them on social networking or photo sharing sites.
Anything that can be viewed on the screen can be copied through the analog hole of just taking a photo of the screen so if it's viewable there's no way to keep it private. (though I'm sure some day all cameras will have built-in copy protection similar to what is used to prevent currency from being copied and all recording devices will use similar schemes to prevent copyrighted audio from being copied, thereby closing the analog hole)
I have seen really terrible performance on real hardware RAID cards using enterprise-class hard drives. And, yes, I am 100% certain that it was not a fakeRAID controller card.
Hardware RIAD in not a magic bullet for performance and they come with a nuymber of disadvantages (your RAID controller dies: good luck getting the data off the disks).
What kind of workload were you running? As I said, hardware raid is typically faster than software raid, especially for writing to RAID-5/6 volumes. If your workload is mostly read-only, then you may not see much (if any) improvement with hardware RAID.
I use RAID to protect me from server downtime more than to protect my data - even if I have redundant servers, if one server in an HA pair is down, then I have no redundancy left so I use RAID (sometimes with dual controllers), dual power supplies, etc to help ensure that the server stays up. If the server is down anyway, I'm just going to restore data from backup rather than try to recover the data after I replace the card.

In real life? Not as likely as you wish it was, and the inverse square law fully applies. I just don't see this as anything other than a sales gimmick. People should be glad that most things can be charged via USB these days instead of being forced to use proprietary chargers.
If I'm reading their chart right, if the coils are 5cm in diameter, then they just need to be within 5mm of each other for 90% efficiency (5mm / 50mm = 0.1)
5mm seems more than reasonable for a charging mat, even with a case on the phone. That gives you 1mm to cover the coils in the mat, and up to 4m for the case and back of the phone.
A company is only as good as its employees, and having demotivated employees is not good for any company. If the employees are underwater on their stock for the forseeable future, it's going to be hard to keep them motivated.
What part of Zuck's business plan seems to imply he's in it for the long haul?
The fact that he structured the deal to maintain majority control of the company? Why would he institute such a plan (and alienate some large investors) if he wasn't planning to retain control? If he really wanted to cash in his billions and move on, there are better ways to ensure an orderly transition that would have been better for everyone, including himself.
I was talking about the company, not Zuckerberg.
Then no offense, but your interjection to change the subject of this thread to be about the company was somewhat inappropriate, considering the three posts above yours.
No offense, but I assumed that someone would read the first few words of my post: A company is only as good as its employees.
Sorry if that made it sound like I was saying that Zuckerberg's wealth is connected to the health of the company. I kind of thought I made that clear that Zuckerberg doesn't need FB to remain rich when I said Zuckerberg is set for life, there's no doubt
But if changing the topic of conversation within a thread is not permissible, then you should read to the very top of the thread where it was stated that the IPO was a success for Facebook the company: Hardly, the IPO was an amazing success for facebook. And I pointed out that just because they made lots of money doesn't necessarily mean that they made out well. For example, they've pretty much slammed the door on any chance of a secondary offering for the forseeable future.
I know. It is crazy! No hardware RAID is running any sort of software on it, right?? That would be batshit crazy!! It is all baked into the fabric of spacetime.
I trust my single-purpose RAID controller card a lot more than my general purpose operating system to get the write right.
Software RAID can't have battery backup. No sirreee! Those UPS things are not for commodity hardware anyway, only for big iron.
A UPS is not infallible since your server's operating system is subject to other failures such as someone yanking the power cord(s), hitting the reset button on the server, or an operating system crash. A hardware RAID card is not subject to any of these failures, if the power is yanked before it writes data, it will remain in the cache to be retried when the disks are available.
And journaling file system?? That only exists on the hardware from the big 3! Software RAID 1 implodes into a tiny blackhole everytime you run your rsync. Everyone knows that!
Filesystem journalling is independent of RAID level, most people using a journalling filesystem on top of RAID to protect against filesystem corruption from a server crash, which has nothing to do with RAID level. Typically only the filesystem metadata is journalled, so data corruption is still possible even with journalling. (data journalling is possible, but is rare since it means writing a second copy of data. Well actually I guess the RAID controller write cache is somewhat like a data journal)
Another advantage of Hardware RAID is that it's typically much faster than software RAID especially with RAID-5 and 6. Your write only has to hit the cache on the RAID controller to be "complete", while a less-than-full-stripe write with RAID-5 means reading the stripe, calculating parity then rewriting the entire stripe, so each write is really 3 I/O's and the I/O's all have to complete before you can declare the write complete. (I'm assuming NVRAM or battery backed cache RAM, if you use a RAID controller without it then you get what you deserve)
Software RAID has its place, but a hardware RAID controller (a real one, not fake-RAID) adds so little to a typical enterprise server's price that it's generally worth using.
A company is only as good as its employees, and having demotivated employees is not good for any company.
You seem to have a mistaken assumption that his company's employees are his top concern. Considering no one seems to bat an eye at the assumption that he's "set for life", I don't think such altruistic matters concern him in the slightest.
I was talking about the company, not Zuckerberg. The only reason he needs to care about the company so he can keep a few more of his billions of dollars. If he walked away from the company tomorrow, he'd still have billions of dollars to his name (and the company stock would likely drop in the short term, but depending on who takes over, it could help in the long term), but his ego probably won't let him do that - he'll want the company to succeed and grow with him at the helm. But there's pretty much nothing that could happen to the company now that will prevent him from being a billionaire -- it would take an extraordinary act to make the company's stock value to drop far enough to take him out of the billionaire range.
Search for your own. Priced one from hp/dell and it would have cost $6,000 plus. Built it with the same specs for $3000. That right there is why their server sales are dwindling.
The difference is not always so dramatic.
My local whitebox builder can put together hardware equivalent to a Dell R720: dual E-2620 CPU's, 32GB RAM, dual 1TB disks with onboard RAID (i.e. fake RAID) for $2800 with one year carry-in warranty. Dell charges $3566 for the the equivalent server but includes a 3 year next business day on-site warranty.
So the dell costs $766 more, or think of it as $20/month for on-site service.
If you're a large shop (or a very small shop) and don't mind taking care of motherboard swaps, etc yourself, then paying extra for Dell's support probably isn't worth if, but if you're a small shop with a dozen servers, you may not want to dedicate one of your (few) sysadmin's to a day of unracking the server and driving it across town for support, or procuring a replacement motherboard (if it's still available in 2 years) and swapping it out himself.
And when I buy the Dell, I'm less worried about build problems, like leaving a tangle of power cords dangling in front of the cooling fan (which I've seen happen on whitebox builds).
OK only 2% pee!! still do you want to drink it? the analogy is sufficient to make the point, it is not a whole solution to use in a comparison. It's just a way to illustrate to those who are not able to grasp the concept (like yourself or a child).
I'd rather drink a glass of sterile 2% pee than a glass of 2% oil.
